Abstract Background Enteral nutritional supplements are used in many medical facilities and home care, but require appropriate management because they are nutrient-rich products. Recently, infection control methods for Ready To Hang (RTH) preparations, which are widely used and are expected to reduce the risk of infection, have not been established in Japan and are dependent on caregivers. Therefore, we evaluated the difference in the growth of microorganisms depending on the type of enteral nutrients following contamination with microorganisms. Methods Nine types of enteral nutrition were used. Escherichia coli (E. coli) W3110, Serratia marcescens (S. marcescens) NBRC3046, and Candida albicans (C. albicans) IFM61197 were used as test bacteria. The bacterial solution was added to the enteral nutritional supplement, adjusted, and the number of bacteria was measured at 0, 4, 8, and 24 h after the addition of the bacterial solution at 25 °C and in the dark. Results E. coli and S. marcescens grew in RACOL®-NF SemiSolid for Enteral Use, Hine® Jerry AQUA, and Mermed Plus® over a 24-h period; however, a decrease was observed for other enteral nutrition products. In contrast, C. albicans grew in all enteral nutrition products. Conclusion Because the viscosity and calorie content vary among enteral nutrition preparations in which growth was observed, we found that pH had the greatest effect on the differences in bacterial growth. Nonetheless, C. albicans growth occurred in all nine types of enteral nutrients, indicating that unlike bacteria, its growth was independent of pH. If semi-solid enteral nutrients are contaminated with microorganisms for any reason, microorganisms will grow, so appropriate infection control is necessary to prevent infection.

Community cooperation pharmacies are equipped to prepare narcotics and sterile injectable drugs for palliative medicine at home for cancer pain and end-of-life care; however, to the best of our knowledge, the actual status of the system to provide palliative medicine at home has not yet been examined. Therefore, in this study, given that home palliative medicine is one of the accreditation criteria for community cooperation pharmacies, a questionnaire survey was conducted among managing pharmacists engaged in community cooperation pharmacies to investigate the actual status of the system to provide appropriate services, mainly pain management, to patients who need home palliative medicine. An analysis of responses to the questionnaire showed that pharmacists working in community cooperation pharmacies had a high level of understanding of the proper use of rescue doses of medical narcotics and patient guidance. Pharmacists with experience in sterile and injection preparations also had a high level of understanding of palliative medicine. On the other hand, they had a low level of understanding of the WHO method for cancer pain treatment and appropriate suggestions for opioid switching. These results indicate that the creation of learning opportunities, such as training on injectables and prescription designs, for pharmacists in community cooperation pharmacies is one of the measures that may improve their understanding of palliative medicine.
